This is the ultrasonic jewelry cleaner that uses 42,000 Hz of ultrasonic sound waves to remove 99.8% of the debris from rings and necklaces. The Hammacher Schlemmer Institute soiled earrings, rings, and necklaces with a mixture of hair gel, hand lotion, and dirt and placed in an oven to solidify the detritus. An independent testing laboratory then weighed each piece after the soiling process and again after one cycle in this ultrasonic cleaner to confirm that it had removed 99.8% of the debris. The jewelry cleaner's ultrasonic sound waves and water (detergent is optional) penetrate deep into crevices and safely and effectively clean intricate areas of bracelets or watchbands. With an easy-to-follow instruction manual, a crystal clear LED screen with a digital timer, a watch holder, and an easily accessible 18-ounce water reservoir. 5 1/2" H x 8 1/4" L x 6" D. (3 lbs.)
